Inventor: ELLIS JOHN WYNDHAM
IPC: H02K7/118
Filed: 1951-06-18
Abstract: 706,994. Ensuring uni-directional rotation. SMITH & SONS (ENGLAND), Ltd., S. May 23, 1952 [June 18, 1951], No. 14366/51. Class 80 (4) A device for ensuring the rotation of a synchronous electric motor in one direction only comprises a bush 3 with an eccentric bearing surface 4 about an axis X secured to the shaft 2 of the motor 1 of the type used in elec-. tric clocks. Supported on the surface 4 is a member 5 having 180 degrees of lost motion therewith controlled by a pin 8 co-operating with a stepped plate 7 secured to the bush 3. A light frictional drag is applied to the outer surface 6 of the member 5 by means of a U-shaped member 9 secured to a fixed pin 10 so that according to the direction in which the motor is started the pin 8 of member 5 moves against one or the other of the shoulders of the stepped plate 7 and assumes a position at a greater or lesser radius with respect to the shaft 2. In the position of greater radius the pin 8 engages an arm 13 also secured to fixed pin 10 so that rotation in that direction is prevented and an impulse given to reverse the rotation. With the pin 8 in the lesser radius position describing a circle 11 it clears the stop arm 13 and free rotation in the corresponding direction is permitted.

Title: Improvements in or relating to fluid operated brake mechanism
IPC: B60T13/24
Filed: 1934-05-12
Abstract: 438,363. Fluid - pressure brakes. STITT, R. R., 1929, Glendale Avenue, Detroit, Michigan, U.S.A. May 12, 1934, No. 14403. [Class 103 (i)] Valve mechanism for fluid-pressure brakes comprises parts connected respectively to the brake piston and to the pedal or equivalent to give a " follow-up " action and a piston or equivalent subject to the opposing pressures of the cylinder and a spring and interposed in the parts to accelerate the follow-up action and assist in maintaining the cylinder pressure for a given position of the pedal. The valve casing 4 is connected by rod 12 to the brake operating shaft and a rod 14 to which is secured the valve-operating finger 19 is connected to the pedal. The finger 19 is adjustably secured to the rod 14 by nuts 18 and a sleeve 17 which slides in the casing. The casing 4 is connected by a union 28 to the supply reservoir and by union 27 to the brake cylinder. The chamber 41 is connected by a pipe (not shown), to chamber 271 and thus to the cylinder. An inlet valve 32 is operated by finger 19 through a spring 40 engaging an abutment 38 on the valve stem 34 which is fluted to provide access from the supply to chamber 41. The release valve 44 having a stem 48 controls communication between chamber 27<1> and chamber 48 having atmosphere ports. A spring 62 may be connected to the casing and to the rod 14 to return the rod 14 and pedal to normal position. A bellows 37 extending between abutment 38 and the casing seals the chamber 41. A piston carried by the stem 34 and having sliding engagement with the casing, may replace the parts 37, 38. Movement of the rod 14 and finger 19 to the left unseats the valve 32 to supply compressed air to the brake cylinder and the consequent movement of the casing 4 tends to reseat the valve, this closing movement of the valve being accelerated by the cylinder pressure acting on the abutment 38 against the spring 40. If with the pedal and finger 19 held stationary, the pressure in the cylinder falls by leakage, the casing 4 moves slightly to the right to open the valve 32 and the valve stem moves to the left to assist the opening of the valve until the pressure is restored. Mechanical operation of the brakes may be effected by causing the shoulder 50 on the rod 14 to engage the casing 4. Return movement of the rod 14 causes the finger 19 to open the valve 44.

Abstract: 894,970. Thermonuclear apparatus. C S F COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 26, 1960 [May 14, 1959], No. 14545/60. Class 39 (4). A plasma confining device including an evacuated toroidal envelope, means for injecting plasma into the envelope, and means for producing a steady magnetic field extending around the circular axis of the torus, is provided with means for injecting ultra-high frequency waves into the envelope to propagate within the space between the confined plasma and the walls of the envelope so as to assist the magnetic field in its confining action on the plasma. In the Figure the toroidal envelope 1 is surrounded by six coils 2 which produce a magnetic field generally parallel to the toroid with intensified regions in the vicinity of each coil, thus forming six " magnetic bottles." A waveguide 8 is coupled to the toroid 1 by directional couplers so that U.H.F. electromagnetic waves from an oscillator 12 can be fed to the toroid in a Transverse Electric mode; the high frequency field thus produced in the toroid exercises a transverse force on the plasma which opposes the transverse diffusion of the particles and therefore their escape from the magnetic bottles.

Title: Improvements in or relating to methods of and means for the treatment of steel strip
IPC: C23C2/38
Filed: 1957-05-09
Abstract: 817,667. Coating with metals. TRIGGS, W. W. (Sendzimir, T.). May 9, 1957, No. 14798/57. Class 82(2) [Also in Group XXII] A continuous process for treating work-hardened steel strip comprises bright annealing, cooling under non-oxidizing conditions and rolling while keeping the strip under tension. The strip may be passed through a coating bath of molten lead, tin or zinc prior to being rolled. Strip 1 from an unwinder 70 passes through a welder 71 for joining strips end to end and through a looper 72 into the oxidizing part 73 of a furnace where it is preheated and has its impurities burnt off. It then passes into an annealing chamber 74 with a deoxidizing atmosphere and out through a cooling head 75 and a sealing bell 2 to molten metal coating bath 5. On entering the bath the strip passes round an idle roller 6, Fig. 3, and on leaving, passes first between a pair of rolls 10, 11, submerged partly in molten metal and partly in an upper layer of palm oil or the like and cleaned by scrapers 12, 13 and then through a cooling unit 80, tensioner 77, cleaner 78 and pinch rolls 81 to a coiler 79. The cleaning unit 78 may be omitted and if coated strip is not required, the bath 5 may be left empty and a suitable seal provided at the outlet from the bell. The mill 14 comprises a block with four parallel bored channels for shafts 17 which are accurately supported by members 16 and which carry backing rolls 18 for supporting the working rolls 19, 20. In a modification, the oil bath may fill the whole cavity of the mill 14 and partially fill an outlet hood 46, Fig. 3A, containing partially submerged skimming rolls 41, 42 and submerged concentric jets 47 for discharging under high pressure on to the strip, streams of molten metal surrounded by oil. In another modification the coating bath comprises a chamber 4, Fig. 5, with rolls 23, 24 partially submerged in molten metal 5 so that the metal is lifted into the roll pass through which the strip is drawn. Neutral or reducing gas is directed on to the strip by tubes 26, 27 with a velocity sufficient to blow off excess metal which might otherwise run down into the bell. 2. Gas escaping from the outlet 28 is recirculated and in the recirculation system, may be passed through a bath of molten metal having a high affinity for oxygen. The coated strip then passes to the temper rolling mill 14. Specifications 453,803, 478,360 and 642,767 [both in Group XXII] are refererd to.

Title: Detection of direct currents or voltages
IPC: H04M1/654
Filed: 1975-04-10
Abstract: 1529452 Substation equipment ANSAFONE Ltd 8 April 1976 [10 April 1975] 14882/75 Heading H4K An apparatus for detecting the level of direct current or voltage on a telephone line comprises a first semiconductor device which emits electromagnetic radiation proportional to the current flowing through the device, a second semiconductor device which receives the radiation and generates a proportional current, means for connecting the first device between the two conductors of the line and means for detecting the current flowing through the second device and producing an output signal proportional to the current in the second device and hence proportional to the current or voltage on the line. In the embodiment, Figs. 1A, 1B, the apparatus is used in a circuit for connecting a telephone answering machine to a subscriber's set. LED D5 is connected between the conductors L1, L2 via a rectifier bridge RB and a voltage monitoring circuit, comprising resistor Rl, or a current monitoring circuit CM comprising resistor R14, thermistor TH and capacitor C5; R14 and TH limit the current through LED D5, which together with phototransistor TR1 from an optical isolator OI. The output of TR1 is compared with a reference by comparator 1, whose output is connected to NAND gate G2 and to the control of the telephone answering machine. The other input of NAND G2 is fed from a ringing detector RD through a comparator 2 and a timer TIM 1. Timers TIM2 and TIM 3 are used to delay the connection of the machine to the line to allow time for the subscriber to answer a call himself, if present. Contacts (HL1, HL2, Fig. 2, not shown) may be provided for connecting the line, through transformer T, to a recording apparatus for recording a telephone conversation. The machine may be used with subscribers connected to automatic or manual exchanges. Operation.-Figs. 1A, 1B show the state of the circuit for the "stand-by" condition. If a dialling or ringing signal appears on the conductors L1, L2, relay ML is operated through detector RD comparator 2, timer TIM 1 and gates Gl, G2, to connect the voltage monitoring circuit VM to the isolator OI which thus, through comparator 1 detects the voltage on the line L1, L2; comparator 1 also indicates whether the detected voltage is above or below a reference value, which indicates whether a dialling or ringing signal is present, as shown in Fig. 3. Timer 2, at the same time, is started and if the subscriber does not answer within the timer's running time for a ringing signal, the loop line relay LL is operated to connect the answering machine to the line. LL operating connects the current monitoring circuit CM to the isolator OI and the current on the line is monitored. If the subscriber lifts his handset, while the machine is connected to the line, the change of current in the line is detected and the machine is disconnected from the line. A loudspeaker in the machine may be connected to the line while the machine is recording a conversation, so that the subscriber may listen to the recorded conversation.
